Keynote speakers: Wireless power transfer: From long-distance transmission to short-range charging

Since Nikola Tesla proposed the Wardenclyfee Tower in 1889 for the wireless power transmission to date, it has been over a century. The idea was later picked up and implemented continuously in the last half a century. Recently in 2007, MIT research group picked up the old concept and implemented for potential applications into telecommunications. This talk will address briefly the state of-the-art research and development progresses in the wireless power transmission technology and also potential applications. The talk is categorized into two aspects, that is, (a) the long-distance and high-power wireless energy transmission and (b) the short-range and low-power wireless energy transmission. For the long-distance high-power transmission, the talk will cover atmospheric effects, high-power microwave generation, transmitting antennas, EMC/EMI effects on radio frequency wireless system, rectennas, and biological effects on human being and animals. For the short-range wireless power transmission, the review will touch inductive couple effects and their applications onto power-grid systems, wireless power charging systems, mine-tunnel power charge system, and medical applications. The talk will, of course, discuss on advantages and short-comings of these proposals.
